Since the second mounting hole 102 is formed in the body 10 and the hole wall is integrally formed with the body 10, the wall thickness of the second mounting hole 102 is mainly controlled at the portion where the wall thickness is smallest. For example, the thickness between the second mounting hole 102 and the main oil gallery 60 is set to be as small as possible, so that the second mounting hole 102 and the main oil gallery 60 are as close as possible, and the increase in volume caused by an excessively large distance is avoided; the thickness between the part of the second mounting hole 102 extending into the boss 103 and the outer side wall of the boss 103 is set to be as small as possible, so that the volume of the boss 103 can be reduced; the thickness of the second mounting hole 102 toward one side of the outer wall of the main body 10 is set as small as possible to reduce the volume of the main body 10, which is advantageous for the weight reduction of the engine.

The diameter of the second through hole 501 is larger than or equal to that of the first through hole 401, so that the oil is prevented from entering the first through hole 401 from the second through hole 501 to generate a pressure drop.
